This menu item sets the pixel aspect ratio relative to that of the input video.
Select analog 4:3 when you are working with normal aspect ratio video and you want to define the 4:3
aspect ratio according to the nominal analog blanking.
Select analog 16:9 when the input video has been compressed from a 16:9 format to a 4:3 format and
you want to define the 16:9 aspect ratio according to the nominal analog blanking. Objects will be drawn
in their compressed state, so that they will appear normal when the video is expanded again.
Select digital 4:3 when you are working with normal aspect ratio video and you want to define the 4:3
aspect ratio according to the clean aperture.
Select digital 16:9 when the input video has been compressed from a 16:9 format to a 4:3 format and you
want to define the 16:9 aspect ratio according to the clean aperture. Objects will be drawn in their
compressed state, so that they will appear normal when the video is expanded again.
3.2.5. Choosing the Object Blink Time
Obj blink =
short
This menu item sets how long objects blink when they are selected.
Select long when you want a selected object to blink for twenty seconds before it reverts back to being
displayed continuously.
Select short when you want a selected object to blink for three seconds before it reverts back to being
displayed continuously.
Select none when you want to disable object blinking.
3.2.6. Choosing How Line Numbers are Displayed
Ln disp =
int rel
When the selected video standard uses an interlaced raster, this menu item changes the format that the
front panel display uses to show line numbers.
Select int rel to view line numbers in an interlaced relative format. In this format lines are numbered
relative to the beginning of each field and shown with their field number. (E.g. in 525 line video, line 21F1
is the first line of active video in field 1, line 21F2 is the first line of active video in field 2)
Select int abs to view line numbers in an interlaced absolute format. In this format lines are numbered in
an interlaced raster with the line numbers relative to the beginning of the complete frame. (E.g. in 525 line
video, line 21 is the first line of active video in field 1, line 283 is the first line of active video in field 2)
When the video standard uses a progressive (non-interlaced) raster, this menu item is not available. Line
numbering is always done in a progressive system referenced to the beginning of the frame.
